Abstract: An embodiment of the present disclosure relates to an apparatus for synthesizing nanoparticles by irradiating, with an electron beam, a nanoparticle aqueous solution in a reaction vessel provided inside a shielding chamber, and more particularly, to an apparatus for synthesizing nanoparticles, which is capable of preventing radiation generated in a shielding chamber from leaking out, and facilitating maintenance and repair.

Abstract: Provided are a catalyst for a fuel cell, a method of manufacturing the same, and a fuel cell including the same. The method of preparing the catalyst for a fuel cell does not use a chemical reducing agent and therefore does not require a separate post-treatment process. In addition, through heat treatment, the structural stability of the catalyst and the active point of the oxygen reduction reaction are improved, and long-term stability can be achieved.

Abstract: Provided are an oxidation-resistant catalyst for fuel cells, a manufacturing method thereof, and a fuel cell including the same. In the case of the catalyst for a fuel cell according to the present disclosure, the fuel cell catalyst according to the present disclosure has oxidation-resistant features of a metal oxide while maintaining the electrical conductivity of a carbon support. Accordingly, catalytic activity of platinum particles, which are the active points in fuel cells, can be improved, and metal oxides can prevent platinum particles from directly interacting with carbon supports, thereby resolving the problem of carbon corrosion at the platinum/carbon interface.

Abstract: Provided are a high-crystallinity, porous, and hydrophilic catalyst for a fuel cell, a manufacturing method thereof, and a fuel cell using the same. The method of manufacturing a fuel cell provides a new carbon support composition having the following features: supporting of metal compounds by electron beam reduction of metal precursors, improvement of mesoporosity and dispersion of crystalline carbon obtained by metal vaporization by sequential low-temperature heat treatment, and improved performance stability in a low-humidity atmosphere.
